SPECIFICATION.

'ro ALL .WnoM 1T MAY-GONCERN:

4 Be it known, that I, ALBERT SQCLARK, of' Dryden, inthe county of'Tompkins, in the State of New York, have invented a new and improvedSled Brake; and I do hereby declare that the following is a full andexact description ofthe same,

reference being -had to the annexed drawings, making a part of thisspecification, L

Fig. 1 is a plan view=or longitudinal elevation'.

The nature of my invention consists in providing` a. sled'or sleighwitha brake oi' such construction as to operate with great power, and at.the same time -to require but slight exertion from the operator 'tokeep it ina most effectual postion.-

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents a sled of ordinary construction. B is the lever foroperating the i brake, which is secured to the rocking bar C by being'inserted in a hole madetherein. Throughjh'e rave 1J b a longitudinalslotis made forthe admission of' the lever B, and. to provide for itsufficient room to operate. C is a rocking bar, secured to the rave 6 b-by means of' suitable bearings, as at a. i

E is a link connected to the arm cA of the rocking bar C, and also totheclaw f, by the arm D. The arm D and claw f are made of one piece andysecured to the runner G, in any proper manner that Will admit of' af'ree play upon its fulcrum o.

s is a slot in the arm D, through which the' pin z' passes loosely, soas to admit of asliding motion, and is secured by riveting the ends uponeach side of the link E. H isthe middle bearnof' the sled, with which4the link-E comes in contact when operated, and serves as an eti'ectualmeans of keepin g down the claw f.

O'Zarks Improved Sled Bra/ce.

In the above description it Willbe seen that by throwing forward thelever B, it

f actuates the claw f by the movement of the link E, Which operates inthe slot s ofI the arm D, as an inclined plane, and is held down bysliding under the projecting beam H. The lever B is fitted into therocking bar C, with a tapering-form, which admits of its being easilyWithdrawn when logs or other heavy loading is required to be rolled onthe sled, and replaced with facility when required.

What I claim as new, and desire to secure by Letters Patent', is-

'lhe combination of link E and beam H' with the slotted arm D, the Wholebeing constructed and arranged as and for the purpose herein shown anddescribed.
